UNITED STATES PATE :PETER E. MORAN, or wooDwARn. rev/'Alf ELvAToR, DUMP STRUCTURE.

' to an auxiliary Hoor door operating device, operable upon the 4movement of the dump structure from one position; toits dumping floor door.

floor door operating device upon the dump structure itself, so that the floor door may 2 be moved toward closed position in case the against, when it is moved to dumping position.

With these and other objects in view, my invention consists in thefconstruction, arrangement and combination of the various parts of my device,y whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my drawings, in which:

Flgure 11s a sectional view taken through an ordinary dump structure used in grainy elevators. with my improved floor door op# erating device attached to one of the dump floor members. v

Figure 2 is a similar, sectional view with parts shown in position where a `wagon or truck -is being dumped, the dotted lines showing the floor door operating devicein the wagon' or truck strikes thereagainst.

Figure 3 is a sectional view taken on line 3-3 of Figure 1, parts being broken away to better illustrate the construction.

In the accompanying drawings, 'I have vused-the reference numerals 10 and 11 to in@ More particularly, my invention relates position for thereby-raising the auxiliary Still a further Objectis to so mount theI rear end of the wagon ortruck strikes there# l claims, and illustrated in the accompanying' `portion ofl position 1t will assume yas the rear' end of n Application `1ed June 6, 1924. Serial No. 718,323.

dicate the two floor dump members lof* an4A The 'dump lfloor ordinary dump structure. 1Q is hingedly supported by means of the` hinge 12. The two dump members 10 and 11 are connected together by a hinge 13.

The free end of the dump 11 has a pair of,v

rollers 14 secured thereto, which ride in tracksor grooves115.

The dump members 10 and 11 have a number of supporting beams16 upon which rest NT oFFlca i the floor boards 17. The fdump'members 10` and 11 are capable of movement to position where the hinge 13 will be moved downwardly lwithin the ypit 18,"and the parts assume the position shown in solid lines inV Figure 2 ofthe drawings.

The dump membersy 10 and 11 are raised or lowered by anysuitable means. l

The lparts just described, are of the ordi-y nary construction and form nopart ofmy vpresent invention except that my floor door operating device cooperates with the partsI just described.. f v

. A truck 19, having wheels 20, is shown in dumping position in Figure 2 of the drawings.

lThe'graln passing from the truck19 will*` pass into a chute or bin 21. The bin 21 is coveredwith. a door member' 22v which can ibe moved to inclined position, or to horizontal position where it will serve as a floor when the trucks pass thereover as shown in Figure v1. The door 22 is hinged (not shown in the drawing) and is swung upwardly'in the'direction of the arrow 228L while dumping-the truck. Y

In a' great many cases, when kthe truckl is about to be dumped, quite a bit of grain will drop'on tothe floor between the dump members 10jand 11, and the chute or binjust rearwardly of the .truck,and my floor door operating device is designed to raise a small the floor below the rear end of the truck or wagon, which servesas a chute jfor causing all of the grain to ypass'into the bin or'hop'per provided for the purpose.y Y

I have referred to the portion of theoor between the hopper or bin 21, and floor dumping member 11,.by the reference numera-125.

The oo'r 23 mayproperly be called aioor door, and is hingedly mounted by means of a hinge 24.

Ybars pass therebetween;A

My ioor door operating device consists of a pair of pivoted links 25 supported from the under side of the floor dump ll on the beams 16.v v f .l

Secured to each of the lower ends of-the .links 25 is a door operating rod or bar 26. The bars 26 andlinks 25 are connected to,-v grether by means of a transverse shaft 27.

he shaft 27 extends from one-of the links- 25 to the other of the links 25 so that'tlie two sides of the door operating vdevice may operate in unison.

Y Secured to the forward ends of the bars 26'arethe rollers 28 inounted'on a'transver'se shaft 29, which also. extendsfrom one side ofthe device "to vthe other `for retaining the ends of' thefbars iii-'properv position, and for-permitting them to `operate together..

The `i-o1lei's28- ride `against two ybeams mounted on the underside ofthe floor In orderto: retain the' barsv26 in proper position, If provide' uide brackets 31., which are secured to the ams 16, and have' the A roller A32 ongthe bottom end of each of the guideibrackets firetains the bars in the guide brackets'31' and `helps their easy passing therethrouah.'v y .n

A coil springv 331ii's' fixed to each of .the links 25 and .have their' free ends connected totheguide brackets 31. v Thef coil springs 3344 cause the bars 26 to Y bev moved inthe direction'indi'c'ated' byuthB arrow 34, for, insuring the rollers '28 to' en" gage the i'inder'side of 'the beams. 30.

' Stop pins r35 are'irn'oi'inte'dv onthe bars 26 and limit the amount of movement of theV bars-26in the direction indicated' lbythe arrow-34. j V. The bars 2 6, however, may be -moved in the direction oppositel from' the arrow 34, against theaction of. the springs 33, as will hereinafter be more fully set forth,

y Practical operation,

` In the.practicaioperation of'my invene tion, after a truck yhas been positioned with therear wheels .20 upon the dump floors I0 andfll, the .dump floors T1() andlvlare moved v`to..y the-position shownin Figure l2 -of 1 the drawings, .which will cause therear end of the"y truck f :to be lowered so that the 'bottom thereof is in inclinedr position;`

The door 22 is moved' toY open .position so' f that the grain discharged from the truckwillpassinto the hoppen21. l n As the-dumpfloorV 1l is moved from position showninFigure'` 1 ofthe drawings,

to positionshown-in Figure r2 ofthe draw ings, iti-will carry j with it the: door operateing device and the rollers 28 will ride ,against the. beams`f130.,ausing the door 23 "to lbfe "would assume the position? in 'lines in Figure 2 of the drawings".

akind that thewbox thereof would move to position shown in dotted lines 36, then the floor 'dooril23 would' not be permitted to raise the full distance, and the springs 33 would become extended, vand the l doorr door as well asr the operating device therefor,

doaeaf o When the wagon` ortrufci: is removed* from the dump vstructure, the lsprings would cause the bars to assume their normalposition, and .when the dump iioors'; 10 and 11 areieturned to normal position, asshown `f in Figure i, the door S23-would be4 permitted to dropto lits closed or normal position.V l.'

The door -23 serves as a chute-between'gthe sures all of the grain yfrom-passing into the binor hopper.

' .rear end of the 'wagon or truck .Tand/the" orf ward end ofrthe hopper or Abin/'21, and in- Ity may be here'mentioned'that-in agreat `many cases, where theendof the lWagoner truckr lis short, the; 'grain ordinarily-falls on to the Hoor and is just as likely to pass im the'dump pit leas.I int-0 the proper YSome changes may beV made inv Athe con-'- structionl and-,arrangement ofI the various parts y"of --my -inventionwithout departing,
